Elixir Full Syn GL-5 75w 90 Gear Oil 1Qt

The Elixir Full Synthetic GL-5 75w 90 Gear Oil is engineered for high-performance differential and transfer case applications where extreme pressure protection is non-negotiable. Whether you're running a stock truck, a heavily modified off-road build, or a weekend track machine, this synthetic formulation delivers the film strength and anti-wear properties that differentiate quality gear oil from budget alternatives. Designed to handle both highway cruising and aggressive terrain, this 1-quart bottle fits seamlessly into a complete fluid maintenance program for serious vehicle enthusiasts.

AMALIE's full synthetic technology provides superior thermal stability and oxidation resistance compared to mineral-based oils, translating to extended drain intervals and reliable performance across temperature extremes. The GL-5 specification includes robust anti-scuff additives that protect ring gears and pinions during high-torque events—critical for vehicles running aftermarket differentials or operating under sustained load. Synthetic base stocks also shed heat more efficiently, reducing gear wear during towing, traction-limited acceleration, or constant engagement in low-range four-wheel drive. The 75w 90 viscosity grade balances cold-start fluidity with hot-running film strength, making it compatible with most modern limited-slip and locking differentials.

This product is ideal for owners of trucks, SUVs, and performance vehicles who perform their own fluid maintenance or top up between full service intervals. The 1-quart size accommodates partial refills, differential top-ups, and transfer case servicing without excess. Mechanics and DIY builders regularly stock this specification to meet the demands of factory differentials, aftermarket lockers, and modern electronically-controlled systems. Always verify your vehicle's factory recommendation before use; GL-5 is the standard for most modern differentials, though some older vehicles or limited-slip units may require GL-4. Proper disposal of used gear oil is essential—never pour down drains or into soil.
